Modifying existing particles with particle properties

Is there any way to modify particles based on the properties of the particles themselves? What I'm trying to do is modify a particles x/y movement dependent on its height. I want the particles to move faster if they're higher in the air, based on player input(walking).

This is my attempt:

PHP Code:


		
			
  temp.emitter = findimg(200).emitter;

  if (abs(temp.dx) > 0) {

    with (temp.emitter) {

      addglobalmodifier("once", 0, 5, "x", "add", -temp.dx*particles[0].z,-temp.dx*particles[0].z);

    }

  }

But obviously it doesn't work or I wouldn't be here.

I don't think so. There's no way to read or write the variables of particles; fairly literal fire and forget.

The particles[] array you're accessing is just templates/prototypes/classes which hold the starting variables of the actual particles.

You could maybe be dynamic with the modifiers though by repeatedly doing removemodifiers() and add*modifier() but I'm not sure how well that works or if it could get laggy.
